/*  Nov 6, 2003  Initial version.

 *

 *  NOTE: This implementation is quite strict about requiring all

 *    field seperators.  It also does not allow leading whitespace

 *    except when processing the numeric fields.  glibc is more

 *    lenient.  See the various glibc difference comments below.

 *

 *  TODO:

 *    Move to dynamic allocation of (currently staticly allocated)

 *      buffers; especially for the group-related functions since

 *      large group member lists will cause error returns.
